Measuring Stations: Type AFS, AFQ</b></font></p>
<p align="left"><font face="Arial" size="2">Barcol-Air manufacture
a sophisticated range of units for all ductwork sizes for controlling
pressure and accurate air volume measurement.</font></p>
<p align="left"><font face="Arial" size="2">These units can be used
for laboratory applications to balance supply and extract volumes
on extract hoods etc. or in standard buildings.</font></p>
<p align="left"><font face="Arial" size="2">They are of particular
use in multi-floor, multi-tenanted buildings where system air / pressure
can be shut-off, monitored, changed etc. to suit floor occupancy.
Tenant billing can be programmed via the BMS from these units showing
how much air has been used each min/hr/day etc.</font></p>
<p align="left"><font face="Arial" size="2">All in all a total energy
efficient flexibility is built into any project system by using
the above.</font></p>
